WILLIAM E. QARIVEAU, OF ST. PAUL, MINNESOTA.

PRIMER AND STARTER.

To all whom it may concern Be it known that 1,- WILLIAM E. OARIVEAU, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Primers and Starters, of which the following is a specification.

This invention relates to a priming and starting device for internal combustion engines, and the object of the invention is to maintain equal pressure in all of the cylinders, to make positive the starting of the engine without releasing any of the cylinders of their compressed charges, and furthermore to provide a device of this kind in which a storage tank is provided for each engine cylindervand in which said storage tanks can be recharged either while standing or running on a level or down grade.

With the above objects in view the inven tion consists of the novel features of construction hereinafter fully described, pointed out in the claims and shown in the accompanying drawings, in which:

Figure 1 is an outline perspective view of my starting and priming mechanism, portions of engine cylinders andvan automobile dash board being shown in dotted lines. Fig. 2 is a detail sectional view of a regulating chamber and parts attached thereto, a float operated needle valve being shown in elevation. Fig. 3 is a vertical section through a valve casing and lever operated slide valve. Fig. 4 is a detail elevation of the valve shown in section in Fig. 3. Fig. 5 is a longitudinal section through a check valve casing, the valve and spring being shown in elevation. Fig. 6 is a sectional view of a check valve elbow, with the valve and spring shown in elevation.

In these drawings 1 represents the front of the dash board portion of an automobile and 2 the various engine cylinders, portions of four of which are indicated by dotted lines. A carbureter 3 has connected thereto a brace tube 4:, which extends horizontally from one side of the carbureter withwhich it communicates at one end just below the normal gasolene level, the said normal level being indicated by a dotted line, the other one of the tubes being closed. lhis tube is provided with four openings upon its under side, one of which is shown in detail in Fig. 2, and inserted in each of these openings is a plug 5 provided with a tapering bore in which works aneedle valve 6. The lower 9 Specification of Letters Patent.

end ofthe plug 5 is threaded into a brass cylinder 7, which if desired may be provided with a detachable bottom. There are four of the cylinders 7 which form regulating chambers and which communicate with one of the openings 41 in the tube 1, and each cylinder 1s provided with an upper opening 8 and a lower opening 9. Adjustably secured upon the needle valve 6, by means of suitable nuts and Washers and working in the cylinder 7 is a float 10 which may be of any suitable material such as cork.

Each cylinder 7 is connected through the lower opening 9 with an inlet valve 11 of one of the cylinders by means of a tube 12 each cylinder is also connected indirectly to a storage tank 13 by means of a pipe or tube 14. It will be noted therefore that each engine cylinder is connected to one of the regulating chambers formed by the cylinders 7, and each of said chambers has valve controlled communication with the carbureter through the tube 4 and is also in communication with one of the storage tanks. As soon as the predetermined amount of gasolene is fed from the carbureter to a cyllnder 7 the float 10 will commence to rise and when the supply reaches a certain level in the cylinder 7 the needle valve will seat itself at the upper end of the plug 5 and will cut ofi' communication between the engine cylinder communicating with that particular regulating chamber and the carbureter, thereby insuring an equal supply of fuel for each engine cylinder.

Upon one cylinder of the engine is arranged a supplemental valve casing 15 which is connected by means of a pipe 16 with certain check valve casings 17, one of which is illustrated in section in Fig. 5, each of said casings comprising a ball check valve 17 and spring 17 The valve casings 17 inserted into suitable Ts 18 each of which carries a vertically arranged valve casing 19 in the bore of which works a slidable valve stem 20 provided throughout its lower portion with a bore 21 which opens laterally adjacent each end through the side of the stem. The lower end of the stem carries a disk valve 22 which works in the T 18 and the upper portion of the stem projects above the casing 19 and is slotted as shown at 23 to receive the cam end 24 of a lever 25, these levers are pivoted midway their ends upon suitable lugs 26 carried by the casings 19, and the levers and stems 20 are held in their normal positions as shown in Fig. 2 by means of springs 27. Suitable pipe sections 28 ing bar 3 1. This last mentioned bar is connected to one arm of the bell crank 35 mounted upon the front of the dash board 1, and the same arm is also connected by means of suitable links 36 with an electric switch 37 which when open breaks the ignition circuit of the cylinder carrying valve 15. The other arm of the bell crank 35 connected by a suitable link 38 with a foot operated lever 39. A second bell crank 40 also has one arm connected to a link 41 which in turn is connected with an operating lever 42. The link 11 also carries a bar 43 which is operatively connected to the lever 25 previously described. The other arm of the bell crank 40 connected by means of a suitable link 44 with a common operating bar 32 of the valve operating handles 31.

It will be obvious from the above that upon depressing the inner end of the foot lever '39 the rocking of the bell crank 35 will open the switch 37 and will also open the valve 15, thereby charging the storage tanks 13 from that engine cylinder which carries the said valve. As soon as the foot lever is released the valve 15 will be closed by a spring 45 and the switch 37 would also be closed reestablishing the ignition circuit of the said cylinder.

Upon depressing the foot lever 12 the bell crank 40 will be locked thereby opening all of the valves 11, and the bar 43 will be lifted thereby depressing all of the levers 25 and admitting an explosive mixture from the storage chambers 13 through the valve stem 31 and throughthe pipes 1 1 to the regulating chambers 7 from which each engine cylinder 2 will be fed according to its requirements, said feed being regulated by the floating needle valve 6. All cylinders are there- "fore at all times charged with an equal pressure and a positive starting and priming device is provided.

What I claim is.

1. The combination with a multiple-cylinder engine, and a carbureter, of a series of regulating chambers equal in number to the cyllnders, each of said regulating chambers having valve controlled communica .tion with the carbureter, and an equal number of storage cylinders, each storage cylinder having communication with one of the regulating chambers, and each regulating chamber having communication with one of the-engine cylinders.

2. The combination with an internal combustion engine having aplurality of cyl- 3. In a device of the kind described, a

seriesof storage cylindersequal in number to the engine cylinders, each of saldstorage cylinders having communication with one of Y the engine cylinders, a supply pipe running from one of the engine cylinders and adapted to feed all of the storage cylinders, a valve regulating passage of fluid through said pipe, and means for breaking the ignition circuit of said engine cylinder when said valve is opened and for automatically completing said circuit upon closing of said valve.
